This invention relates to footwear and more particularly to the sole andheel-thereor.

The conventional types of leather or ruba her heels and soles employedin footwear at the present time possess numerous disadvantages,primarily due to the material and manner in which they are made. v Heelsand soles made of leather are hard, non-shock ab- 19 sorbing, heatconducting as regards extremes of temperature and in most casesnon-waterproof. On the other hand, heels andsoles made up of rubber,while obviating the disadvantages inherent in heels and soles made ofleather to a certain extent, are nevertheless far from beingsatisfactory, it being well known that the wearing of footwear havingsolid rubber heels and soles is extremely uncomfortable.

a heel or sole, made of rubber or any other suitablematerial andembodying within-its structure a hermetically sealed bag or tubecontaining air under pressure, wherebythe resilient and shock absorbing,waterproof, and due to the layer of dead air therein the degree of heatconductivity under extremes of temperature will be practically reducedto hereunder, proceeds, reference being now hadv to the accompanyingdrawing, wherein Fig. 1 is a top plan view' of the heel, Fig. 2 is adetail plan view of the interior of the heel taken on line 2:2, Fig. 3,and

Fig 3 is a sectional elevational view of the heel taken on line 33,Fig. 1. e

The heel 1, constituting partof my invention, is made conventional inshape andof suitable material and comprises essentially a resilienthousing comprising a top Qand a wall 8 integrally molded therewith andextending completely around the periphery of and f of" diifere'ntmaterial.

The object of this invention is to providesame will render said heel andsole extremely Other objects of thisinvention will become said topportion as, clearly'shown in "2, said wall 3 being of uniform-thicknessand depth throughout. If desired the top portion2 and thewall 3- may bemade separate Formed integral with the wall 3 at spaced intervalsthereof and extending inwardly, in the recess formed by said wall, are aplurality of lugs 4. At each of said lugs 4, and the corners, 5 and 6 ofthe heel, holes 7 are provided for a purposeto be hereinafter described,said holes extending through the entire depth of the wall 3. Each ofsaid holes 7 are countersunk as at 8 on the top 2 of the heel 1.Positioned substantially. centrally within the interior of the heel 1,and molded integral with the top 2 is a depending boss 9, provided witha central hole or bore 7,countersunk at its upper end as at 8 ,thebottom of said'boss 9 being in'the same plane with the bottom of theside- 7 5.

wall 3, as clearly shown in Fig. 8.

In the space or recess formed between the" boss 9 and side wall 3 isinserted a substantially annular resilient inflated member 10,

somewhat on the order of an inner tube. The annular member 10 comprisesa hermetically sealed rubber tube containing airunder pressure,sufficient to withstand the weight-of a .cave portion of said bulge asshown in' Fig 3.

A cover plate 12 made of either rubber or leather and of the samegeneral contour as the heel proper is vulcanized or otherwise securedtothe bottom edge of the wall 3 and boss 7 9 of said heel, said coverplate being provided through the holes 7 and 7 The heads of v said nails(not shown) being driven beneath the surface ofthe top 2 in themannerwell known in the art.

I claim An elastic heel of resilient material comprising a top portionhaving an annular concave-convex bulge moulded thereon, a Wall ofuniform depth and thickness extending around the entire periphery ofsaid top portion and integral therewith, a plurality of spaced inwardlyextending lugs integral with the interior of said Wall and each having avertical hole therein, a centrally disposed vertical boss integral Withthe interior of saidtop portion, an annular tube of resilient materialcontaining air under pressure positioned in said heel and adapted toseat in said concave bulge, and a flat cover plate for said heel adaptedto engage the edge of said Wall, the

engl of said vertical boss, and the topof said tu e.

In testimony whereof I afiix my signature. 7 a BENJAMIN KIND.
